# Use semantic HTML elements
Screen readers use semantic elements to navigate pages—users can jump directly to <main> content or <nav>. Search engines also use semantics to understand content hierarchy.
## Quick Reference
- Use <header>, <main>, <footer> for page structure
- Use <article> for self-contained content, <section> for grouped content
- Use <nav> for navigation, <aside> for related/sidebar content
- Only one <main> per page, but multiple <header>/<footer> allowed
## Check
Review this HTML structure to ensure it uses appropriate semantic elements like header, main, section, article, aside, and footer instead of generic div elements.
